++## MULTILIB_OPTIONS
++## For some targets, invoking GCC in different ways produces objects that
++## can not be linked together. For example, for some targets GCC produces
++## both big and little endian code. For these targets, you must arrange
++## for multiple versions of libgcc.a to be compiled, one for each set of
++## incompatible options. When GCC invokes the linker, it arranges to link
++## in the right version of libgcc.a, based on the command line options
++## used.
++## The MULTILIB_OPTIONS macro lists the set of options for which special
++## versions of libgcc.a must be built. Write options that are mutually
++## incompatible side by side, separated by a slash. Write options that may
++## be used together separated by a space. The build procedure will build
++## all combinations of compatible options.
++##
++## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
++## Makefile will build special versions of libgcc.a using the following
++## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,
++## and -m68020 -msoft-float.

++@opindex mreverse-bitfields
++When enabled, bitfields within a struct are allocated in reverse order.
++This is useful with legacy code that depends on the (inherently
++non-portable) ordering of bitfields via a union. Given:
++
++@smallexample
++struct inner
++@{
++ unsigned int a:1;
++ unsigned int b:31;
++@};
++
++union outer
++@{
++ struct inner inner;
++ unsigned int val;
++@};
++
++unsigned int f()
++@{
++ union outer o;
++ o.inner.a = 1;
++ o.inner.b = 0;
++ return o.val;
++@}
++@end smallexample
++
++a call to @code{f} will return 1 when compiled with
++@option{-mno-reverse-bitfields} (the default), or 2147483648 when
++compiled with @option{-mreverse-bitfields}.
++
++For structures that are a multiple of 32 bits wide, the reversal is
++done 32 bits at a time. For structures that are an odd multiple of 16
++bits wide, the reversal is done 16 bits at a time. For structures
++that are an odd multiple of 8 bits wide, the reversal is done 8 bits
++at a time. The size of a structure (as measured by the @code{sizeof}
++operator) never changes between @option{-mno-reverse-bitfields} and
++@option{-mreverse-bitfields}. Nonetheless, there can be some
++confusing corner cases with structs where the compiler has to add
++additional padding to meet alignment restrictions. Consider:
++
++@smallexample
++struct inner
++@{
++ unsigned int a:1;
++ unsigned int b:15;
++@};
++
++union outer
++@{
++ struct inner inner;
++ unsigned int val;
++@};
++
++unsigned int f()
++@{
++ union outer o;
++ o.val = 0;
++ o.inner.b = 1;
++ return o.val;
++@}
++@end smallexample
++
++a call to @code{f} will return 2 when compiled with
++@option{-mno-reverse-bitfields} (the default), or 65536 when compiled
++with @option{-mreverse-bitfields}. This is because @code{sizeof
++(inner)} is 4 in both cases. In the @option{-mno-reverse-bitfields}
++case, the compiler pads the struct at the end to be 4 bytes long,
++effectively doing:
++
++@smallexample
++struct inner
++@{
++ unsigned int a:1;
++ unsigned int b:15;
++ unsigned int padding:16;
++@};
++@end smallexample
++
++In the @option{-mreverse-bitfields} case, the hidden padding is
++reversed along with everything else, yielding the equivalent of:
++
++@smallexample
++struct inner
++@{
++ unsigned int padding:16;
++ unsigned int b:15;
++ unsigned int a:1;
++@};
++@end smallexample
++
++Of course, if we would rather that @code{sizeof (inner)} was 2, we could
++write the struct as:
++
++@smallexample
++struct inner
++@{
++ unsigned short a:1;
++ unsigned short b:15;
++@};
++@end smallexample
++
++and the padding would go away.
++
++In some cases, especially when using the @code{__packed__} attribute,
++there is no well-defined bit reversal that is possible: the compiler
++will issue an error message in this case. Consider:
++
++@smallexample
++struct invalid
++@{
++ unsigned int f1:1;
++ unsigned int f2:15;
++ unsigned int f3:4;
++ unsigned int f4:4;
++@} __attribute__ ((__packed__));
++@end smallexample
++
++Since @code{sizeof (invalid)} is 3, we are forced to try reversing
++individual bytes in the struct. But f2 is more than a byte wide, so
++we can't reverse it and still have it be contiguous. Similar cases
++occur when dealing with arrays or other large contiguous objects:
++
++@smallexample
++struct invalid2
++@{
++ unsigned char f1[5];
++ unsigned char f2[3];
++@};
++@end smallexample
++
++You'll have to rewrite the affected structs to say exactly what you
++mean in odd cases like that.
++
++Finally, note that individual fields are sized as a whole. The structs
++
++@smallexample
++struct array1
++@{
++ unsigned char f1[3];
++ unsigned char f2;
++@}
++@end smallexample
++
++and:
++
++@smallexample
++struct array2
++@{
++ unsigned char f1a;
++ unsigned char f1b;
++ unsigned char f1c;
++ unsigned char f2;
++@}
++@end smallexample
++
++are not equivalent. When compiled with @option{-mreverse-bitfields},
++they behave the same as:
++
++@smallexample
++struct array1r
++@{
++ unsigned char f2;
++ unsigned char f1[3];
++@}
++@end smallexample
++
++and:
++
++@smallexample
++struct array2r
++@{
++ unsigned char f2;
++ unsigned char f1c;
++ unsigned char f1b;
++ unsigned char f1a;
++@}
++@end smallexample
++
++would, respectively, when compiled with
++@option{-mno-reverse-bitfields}. In particular, f1 is treated as a
++single contiguous 24-bit object for purposes of reversal, while f1a,
++f1b, and f1c are treated as individual 8-bit objects that need not
++(and do not) remain contiguous. Use caution.
